L4 24GB vs L40S 48GB: specs and rental cost comparison
Direct answer
L4 24GB vs L40S 48GB: L4 24GB is cheaper on the lowest tracked rental row at $0.39 per GPU-hour, versus $0.60 for L40S 48GB. That makes L40S 48GB about 54% more expensive per GPU-hour on the cheapest rows in the ByteCosts GPU catalog. L4 24GB has 24 GB VRAM and L40S 48GB has 48 GB VRAM. The tables compare source-backed specs and value metrics only where both GPUs have a real spec field and a tracked rental rate. Rental prices are list rates per GPU-hour, before committed-use discounts, capacity limits, or region constraints.

Frequently asked questions
Is L4 24GB or L40S 48GB cheaper to rent?
L4 24GB is cheaper on the lowest tracked row at $0.39 per GPU-hour, compared with $0.60 for L40S 48GB. Region, capacity, spot interruption, and discounts can change a production bill.
Which is better value, L4 24GB or L40S 48GB?
Use the value table above: $/GB-VRAM is always shown from real VRAM and rental rate, while $/TFLOP rows are shown only when both GPUs have the relevant sourced compute spec. Do not compare a missing field as zero.
Where do these GPU comparison numbers come from?
Rental rates come from the ByteCosts GPU rental catalog normalized from the SkyPilot catalog. Hardware specs come from the committed GPU spec catalog and its per-GPU source URLs.
